To all 1117110717 711; 712.057 (so/warn:

Be it known that 1, ALEXANDER CRAWFORD UHuNowc'rH, a citizen of theUnited States, residing in the borough of Manhattan, city, county, andState of New York, have invented certain new and useful Improvements inMachines for Manufacturing Concrete Piles, Columns, and the Like, ofwhich the following is such a full, clear, and exact description as willenable any one skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specilication.

A concrete or cement pile, column, tie, or the like may be economicallymade and so fortilied and strengthened in its construction as towithstand lateral as well as perpendicular stress and strain bydepositing a layer or coating of cement upon a sheet of wire gauze ornetting and then turning or rolling the same into the form-of a solidcylinder in which the convoluted wire-netting is embedded.

The object of my invention is to provide an apparatus or machine bywhich this method of construction may be carried out and concrete ties,piles, &c., produced in length and thickness required; and my inventionconsists in the devices and combination of devices, as will behereinafter more fully described, and particularly pointed out in theclaims.

Figure 1 is an end viewof a machine or apparatus embodying myimprovements. Fig. 2 is an end View of the same machine, but with themovable parts in different position and showing a partially-rolled pile.Fig. 3 is a plan view of the machine. Fig. A is a plan view of theplatform on which the wirenctting rests, over a portion of which the ce-1nen't is shown as spread. Fig. 6 is similar view of platform on whichrests a partiallyrolled pile, while Figs. and 7 are sectional views ofFigs. 4t and 6, respectively. Fig. 8 is a view in cross-section of aconcrete pile or column completely formed. Fig. 9 is an enlarged view ofgearing for turning the rod about which the concrete-coated wire-nettingis rolled.

The platform 1 is mounted upon wheels or rollers 2 2, which travel overrails or guides 3 3. Above this platform, the upper surface of whichpreferably slants forward, is suspended at a corresponding angle anadjustable platform A by means of frames 5 5, which frames are connected:from one to another by a bar 6 and fitted with rollers 7 7, moving onrails 8 8. To cross-bars 9 9 of these frames, from which extend the arms10 10, carrying the platform 4:, are pivoted lever-arms 11 11, connectedat their upper ends by bars 12 12.

An iron shaft 18, having hearings in supports 141 1 1, extends betweenthe two platforms and is litted at each end with toothed Wheels 15. Atone or both ends of the shaft 13 is a crank-arm 16, and the toothedwheels 15 15 intermesh with toothed wheels 17 17. The wheels 17 17 areprovided with projecting axles 18 18, fitted with sleeves or chucks 1919, to receive and hold the rod 20, about which the sheet ofwire-netting 21 after being coated with cement is rolled.

A wire or rope 22, connected with the upper platform 4: and passingaround the pulley 23, is shown as attached to the lower platform 1, sothat as the latter is moved the former is drawn in the oppositedirection; but this connection is not essential, because the upperplatform once brought in contact with the cement-coated sheet ofwire'netting as it is wound about rod is carried along, thereby exertingcontinuous pressure until the pile is formed. Parallel with the outeredge of the platform 1 maybe conveniently arranged a track 24, uponwhich runs a truck 25 for bringing in the raw cement to spread on thenetting and for removing the cylindrical pile or column 26 after it hasbeen formed.

In operating the apparatus a sheet of wirenetting 21, preferablyreinforced by longitudinal rods or thick wires 27 27 and heavycrosswires 28 28, is spread upon the platform 1 and secured to the outeredge thereof, as well as to the winding-rod 20. This rod is thenfastened in the sleeves or chucks 19 19. A coating of cement 29 isspread over the netting. The crank is turned and through theintermediary gearing a rotary motion is given to the rod 20 and thesheet of cement-coated wire-netting is rolled into a solid cylinder. Asthe roll forms the lower platform is pulled back and platform 1,exerting a pressure from above. is drawn forward. The convolutedwire-netting becomes thoroughly embedded in the concrete and a solidconcrete pile is formed, reinforced to withstand both longitu dinal andlateral stressand strain.

At the end of the operation the upper platform A may be raised bybringing the pivoted lever-arms 11 11 to a perpendicular position andthe pile or column rolled over upon the truck for transportation intothe yard for drying. The article thus produced is in cylindrical form,but before the cement hardens may be readily compressed into rectangularor such other shape as may be desired.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In an apparatus for manufacturing concrete piles, columns and thelike, the combination of a movable platform and means for rolling asheet of concrete-coated wire-netting upon the platform andsimultaneously moving the platform as the pile or column is beingformed.

2. In an apparatus for manufacturing concrete piles, columns and thelike, the combination of a lower platform, means for rolling a sheet ofconcrete-coated wire-netting upon said platform and an upper movableplatform adjusted to press upon the pile or column as it is beingformed.

3. In an apparatus for manufacturing concrete piles, columns and thelike, the combination of a movable lower platform, means for rolling asheet of con crete-coated wire-netting thereon and simultaneously movingsuch platform, and an upper movable platform adjusted to press upon thepile or column as it is being formed.

4. In an apparatus for manufacturing concrete piles, columns and thelike, the coinbi nation of an inclined lower platform, an inclined upperplatform, and means for rolling a sheet of concrete-coated wire-nettingupon said lower platform and in contact with the surface of the upperplatform.

5. In an apparatus for manufacturing concrete piles, columns and thelike, the combination of a lower platform, means for rolling a sheet ofconcrete-coated wire-netting thereon, an upper movable platform adjustedto press upon the pile or column as it is being formed and lever-armsarranged to raise or lift said upper platform away from the column orpile.

6. In an apparatusfor manufacturing concrete piles, columns and thelike, the combination of a lower inclined movable platform, means forrolling a sheet of concrete-coated wire-netting thereon, an upperinclined movable platform adjusted to press upon the pile or column asit is being formed, and leverarms arranged to raise or lift said upperplatform away from the column or pile.

In testimony whereof I have hereunto set my hand, this 3d day ofJanuary, 1905, in presence of the two subscribing witnesses.

ALEXANDER CRAWFORD CHENOWETII.
